, SIiIDING AND SWINGING WINDOW.

Application led May 19, 1927. Serial No. 192,713.

Thev present invention relatesto windows and their frames, and it belongs to that'class ,0f device in which the sashes are adapted to slide vertically in their frame and also to be swung inwardly within the room. The object of the invention is to provide for a combination of sliding and hinged sashes 1n order that any degree of ventilation may be obtained from that of a slot opening caused 1U by sliding one or the other of the sashes, up to an extreme opening wherein the sashes are swung inwardly within the room to provide an opening substantially equal to the size of the window frame. Another advanr tage of the present device is that the interior and exterior surfaces of the panes of glass contained in the sashes may be entirely cleaned from'the interior of a room. lVhere the present device is employed, a person cleaning the windows is not subjected to any risk and the windows may be cleaned in less time than where the cleaner must reach out or stand outside of the window as with the ordinary sliding windows. I am aware that windows have posed heretofore in which the sashes are adapted to both slide and swing inwardly,

but the purpose of the present invention is to overcome the defects ofsuch prior devices. One object of the present invention is to provide sliding and 4swinging sashes in the window construction and to make the device entirely weather-proof so that rain, snow or sleet cannot penetrate to the interior of the room when the sashes are closed. Another object is to provide a window ,of the character referred to which will eficiently exclude dust and which will not be rendered inoperative or diilieult to operate in the event that dust penetrates between the moving'parts.

Another object of the invention is to provide awindow o'f the type set forth in which the window frame, as well as the sash i `frames, may be made of metal if desired,

and this metal may be made 1n long or continuous strips a-nd .afterwards assembled into the type of structure shown in order' that the cost of making the device principally from metal may be kept within reasonable limits. Another object is to provide a window of the character described which will be easy to manipulate and which will not get out of operating order. Another object of the invention is to provide a window construction of the type described which will be neat in appearance when viewed either from the exterior or interior.y Another object is to provide avwindow having sliding sash frames adapted to be placed in superposed or overlapping position, and while in that position the hinged members of the inner and outer sashes may both be swung into the room, the sections of the outer or upper sash opening into the spaces formed by the opening of the sections of the inner or lower sash. Another object is to provide a construction wherein the sashes will hide the sliding sash frame from view when the window is closed.

Other objects and advantages will be made apparent in the following detailed description of one embodiment of my invention.

In the drawings I have shown a metal frame or window casing comprising a bottom sill 1 atop'sill 2 and side posts 3 all of which may be of metal formed to producev hollow members, one of which is shown adapted to receive portions of the sash members. The upper member 2 of the window casing is shown in cross section in Figures 1 and 4 and it consists of the four rectangular walls 4 one of which is provided with a longitudinal slot 5 facing downwardly, and which is formed by bending flanges 6 in the metal to extend inwardly within the pocket 7; and in the preferred construction, as shown in Figure 4, these flanges are slightly divergent, to receive a longitudinal flange 8 on the upper edge of the sash which closes the upper portion of the window. The flange 8 is adapted to slide in between the divergent flanges the fit of the flange being rather close where it enters the opening 5 and beingr looser above this point, and the flange 8 projects above the flanges 6 when the upper sash 1s in its highest position so that if any dust should work its way in between the flange 8 and the` flanges 6 it can work upwardly over the tops of the latter and thus discharge beyond these flanges. The lower or sill member 1 is also shown made of sheet metal with its top surface 9 inclining'downwardly. and with a raised bead or rib 10 with which the lower portion of the lower sash is adapted to fit to make a water-proof, dust-proof and air tight joint.

The window frame is of sufficient dimen. sions to enclose the upper and Vlower sashes of the present construction. The window construction embodies a rectangular frame for the upper sash and a rectangular frame for the lower sash which move in dierent grooves in the window frame and these frames are adapted to slide past each other.

Each sash frame carries a pair of hinged units or sections in which the transparent members or glass panes are mounted. In referring 'to the sashes as upper and lower sashes I refer to the upper one as the one which is disposed in the higher position when the window is entirely closed, and to the lower one as that which is in the lowermost position when the window is closed, although both sashes are adapted to slide vertically and at times they may be reversed in this relation. For what I call the upper sash there is a rectangular frame comprising` upper and lower horizontally disposed bars 11, 12 which are preferably made of channel metal and therefore U-shape in cross section,

each having a vertically disposed web 13 provided with lengthwise extending beads 14 for stiffening the metal against bending action; and horizontally disposed webs 15. facing inwardly or toward the interior of the room. rlhe lower horizontal bar 12 is of similar construction and similarly disposed. These horizontal bars have projections 16 which have angular extensions 17 disposed at an angle to the lplane of the members 16 and extending into slots 18 formed in the vertical members. of the easement to lie parallel and adjacent to the angular wall 19 which is formed from one member from which the vertical easement member is constructed. The members 17 are connected by the men'ibeis 20 secured along their inner edge, and which is adapted to slidingly engage the cross wall 21 `to guide the sash frame in its verticalI movements and -to prevent the extensions 16 from binding along the edges of the frame'opening 18. These members 20 form the vertical connections between the upper and lower horizontal y bars-of the sliding-frame and, as shown, are enclosed in the easement. I have shown the vertical easement members 22 each formed of a plate 21 forming the side wall, another plate 23 connected with it and forming the outer wall, which plate also bent at an angle to -form the wall 21 vthe portion 24 asis shown in Figure 8. The

plate 29 forms a part of the guideway of the sash frames and the plate 28 which is at tached to it forms at 30 one of the guideways for the sash frames. The plate 28 extends inwardly at an angle as shown at 31 and is then bent again at an angle as shown at 32 to form a groove to receive the edge of theplate 21. There is a vertical slot 32 formed between the plates 29, 27 and vertical pockets 30, 33 are formed by the several plates above described in which and sealing portions of the sashes travel.

The sliding frame for the lower sash member is constructed similar to the frame of the upper sash member and therefore it contains the horizontally disposed channel bars 11 and 1.2 which have extensions 35 which are connected securely at their ends to the vertical bars 36. The extensions 34 extend through the slots 32 Vin the easement members, and the connecting members 36 slidingly engage the plate member 29 in-order to guide the lower sash frame in its vertical movements between the side casement members.

The vertical length of the upper sash frame is somewhat less than the length of the lower sash frame the purpose of which lwill be apparent from the subsequent description. The construction ol the upper sash is as follows: There are horizontal bars 37 of angle metal construction for each section of the upper sash. The upper bar 37 has a flange 38 between which and a strip 89 is clamped the upper edge of the pane of glass 40. The bar 87 also has a horizontally disposed web 41. and a vertically disposed web 42 which is formed willi ofl'sets 43 'extending longitudinally of the bar to form channels or sockets withinv which are received the inner edges ot' the webs 15 which form part of the sliding sash frame. These offsets 43 also serve to stillen the bar 37' in the direction of its length. From the vertical web 42 there extends another horizontal web 44 parallel with the lower web 41 and it is turned upwardly to form the flange 8 which, as previously described, is adapted to slide into the slot 5 formed in the top member of the easement, in order to provide a weather-tight and dust-proof closure between the upper sash and the easement when the window is closed. The lower, horizontal member 45 of the upper sash has a vertical flange 46 against one surface ot which the glass 40 is adapted to be clamped by the attaching strip 47. The bar 45 also has a'hor 'izontal web 48 and a verticalweb 49 which latter is provided with ofl'sets 50 corresponding with the offsets 43 of the upper bar. for" the purpose of providing channels or sockets vto receive the inner edges of the horizontal webs 15 of the sliding frame. The bar 45 also includes a lower horizontal web 51 parallel with the web 48. There is attached to the vertical web 49 of this bar an angular plate 52 which has an upwardly extending flange 53 spaced from the vertical web 49 to provide a slot in which is received a down` wardly extending flange 54 ou a bar which forms part of the lower sash.

The upper' sash is shown composed of two the guiding y sections A and B pivoted respectively on the pins 55 carried by the sliding fraaie so that the upper sash divides along the ce`ntra] line and the two halves may be swung inwardly within the room upon the pins 55. The sections A and B are similarv in construction except for the adjacent overlap- 'ping edges. The section B ll'or instancehas an angular metal bar 56 attached in vertical position along the central line ot' the sash; and this bar has formed in it several angular webs to provide a vertical groove 57 and a vertical groove 58 spaced apart by the in.- termediate rectangular rib 59. The sash section A is provided with a vertically extending bar 60 which is so shaped in cross section as to form spaced gnidii'igribs 61 which are adapted to be received in the vertical grooves 57, 58 of the sash section B when these sections arel swung into closed position, as shown in Figure 1. The inturned edges 61, 61" reach in to the surfaces ol the glass panes to exclude water from entering around the glass.

In Figures 12 and 20 I have shown a latch 62 pivoted to a casing 63 on the sash sectionsA and C andprovided with a locking tongue 64 vwhich ifs .adapted to engage in a slot 65 in the bar member 49 of the sash section A to lock the sections B and D in their closed position or to prevent vertical slidingr movement of the sash frames.

The upper sash sections A and Bare each provided with a curved flange (SG projecting` from the side. edges ot the sash sections near the pivot pins 55; and these flanges are adapted to swing into the vertical slots'ltl of the vertical easement members when the sash members are lswung inta-...closed position; and they are adapted to 'witlnlraw from these slots 18 when the sash sections are swung into open position, as shown in Figures 3 and 11; These closing flanges are provided on both sash sections A andl'facing in opposite `directions, so that each passes into and out of one of the slots 18 in the opposite side members of lthe casemcnt.

The -lower sash is divided into two seetions, C and D which hinge upon the pins 67 carried by the sliding frames of the lower sash, which pins are spaced apart a greater dista-nce than the pins 55 on which the. np-l per sash sections pivot, as is shown in Figure 11. The llower sash sections C and l) are in most respects .similar to the upper sash sections except for the difference in their pivotal points and in certain details, as will be pointedout. The upper horizontal bar of each section C and D corresponds with the horizontal bars of the upper sash sections A,- B; that isv to say, they have a flange G8 against which the 'sheet of glass 69 is clamped at one end by the attach ing strip 70 and it has a horizontal web 7l, the vertical web 78 having ofsets 73 to .form

l nl

channels corresponding with the offsets 43. T his bar also has a horizontal web 74 which carries the flange 54 to receive `the yupper edge of the interlocking flange 53 on the` lower bar of the upper sash member. The tops of the members 48 and 54 are flush, the flange 53 beingshort enough to allow the parts to come into the position shown in Figure 6. The sash sections C and D also have a lower bar 75 having ardownwardly extending flange 76 which tightly engages the rib 10 on the lower sill when the window is in closed position. To the horizontal web 77 of this bar there is secured a plate which has a downwardly extending ilange 78 which engages and lits snugly to the inner surface of the rib 10. This bar also has a vertical web 79 provided with the offsets 8O forming horizontal grooves to correspond with the offsets 43. There is a horizontal web 81 and there is an upwardly extending flange 82 against which the lower edge of the glass 69 is clamped byf the securing strip 83. The sash sections C and D are similar to each other, except for the fact that they are made right and left and except. `for the differences in the vertical strips along their meeting edges. In regard to the. latter feature, it may be pointed out that the section D has a strip 56 along the meeting edge which is in all respects like the strip 56 on the uppersash section B and the section C has a strip 60 in all respects corresponding with the strip 60 on the upper sash sections A; which strips overlap and interlock when the sash sections C and D are closed, the same as the corresponding strips of the upper sash sections, thereby forming' a weather-proof and Adust-proof joint along the vertical centerof the sash sections when the latter are in closed position. The lower sash sections C and D' each have flanges 84 extending in reverse directions at the sides of the sash sections adjacentthe pivotal pins 67 and these flanges are adapted to project into the slots 32 ot the easement members when the sashes are 4in closed position, or when they are swung into-the same yhorizontal plane; and prevent air, moisture anddust from passing around the sides of the sash and yreaching thc room; whereas these side Aflanges withdraw from the slots when the sash sections are gage a pin 89 for the purpose of holding the members A,`-B, or C, D in locked engagement. Preferably, one of these latches is provided at the top of the upper sash sec-- tion or atl the vtop of the section A, another at the bottom of this section A, and still another at the top and bottom of the sash section B, all of these latches being alike in construction'. They serve the purpose of locking the sashes A and B to the Sliding frame to prevent the sections from swinging inwardly except when the latch is released, and they also serve to prevent the sections C and D from swinging inwardly except when the latches are released. If desired, jointed, ivoted links 90 may be attached respectively to the upper sliding frame ,and to the swinging sections A and B for bracing the latter in open position and similar jointed links 91 may be attached respectively to the lower sliding frame and the corresponding sash sections C and D for bracing the latter in open position. These several links are adapted t0 fold into the horizontal channel bars of the sliding frame.

When the window structure isplaced in -closed condition, the sash sections A and B form the closure for the upper half ofI the window and the sections C and D form the closure for the lower half of the window as shown in Figure l, and the several bars have the appearance 0r finish of moulding. When the sash frames and sashes are in the position shown in Figures 1 and 2 the window is entil-ely closed and is held so by the several latches or locks hereinabove described. The flange 8 on the upper sash projects into the Slot 5 So that at this point the window is weather-proof, wind-proof and substantially dust-proof. Where the upper and lower sashes meet a joint formed by the flanges or lips 54, 53 makes a weather-proof, moisture- Y and dust-proof connection. At the bottom the members 76, 78 straddle and contact with the rib 10 on the lower sill, rendering the joint here proof against moisture and dirt. The overlapping and interlocking members 56, 60 of the upper sash members A and B form a weather-proof and dust-proof connection along the medial line of the upper window sash and the corresponding members on the lower sash members C and D form a similar joint at the medial line of the lower half of the Window. 66 project into the slots 18 on the side posts of the easement and prevent the entry of moisture and dust around the side edges of the several sash members. The flanges 84 enter the slots 32- and serve the same pur pose for the lower sash. v

Vith the sash frames arranged in the position shown in Figures 1 and 2, the upper sections A and B may be swung open by first swinging open the section A andthen the section B, the locksor latches being released for this operation. In this instance the sections will be swung into the room, as

.shown in Figure 12, so that the upper half of the window may be partly or fully opened. Likewise the lower sashes C and D may be swung inwardly in the same manner and if The flanges or wings all four sections are opened, the entire window will permit of maximum circulation of air. When the several sections A, B, C, D are in closed position in relation to their sliding frames, the sliding frames and their respective sashes may be slid vertically in the guiding grooves 18, 32 and if desired they may be brought to the position as shown in Figure 3, and then all four of the sash sections may be opened. To accomplish this, 4

the sash sections C, D are first opened inwardly and then the sections A, B may be swung inwardly within the opening formed by the swinging of the sections C, D. As the sections A, B are slightly shorter than the sections C, D, and as is shown in Figure 3, and as the pivotal points'of the sections A, B are slightly closer than the pivotal points of the sections C, D the opening of oneset of sash members within the other', as illust-rated in this View, is made possible.

The members l0a (Figure 10) beyond t-he pivots are merely dummy extensions having the appearance of continuations of the horizontal bars of the upper sash sections. The latter, it will be remembered, have their pivots 55 closer than the pivots 67 of the ower sash sections.

In cleaning the glasses in the several sections the sliding frames may be moved into the position shown in Figure 3, and the inner surfaces of the sections C, D may be iirst cleaned before any lof the sections are opened, and then the sections C, D may be opened o1' swung inwardly, whereupon the outer surfaces of the glasses in these sections may be cleaned within the room. rlhe inner surfaces of the glasses in the sections A, B are then accessible from within the room for cleaning, and after these surfacesl have been cleaned, the sections A, B may be swung inwardly to the position shown in Figure 3, whereupon the outer surfaces of 'the glasses in sect-ions A, B may be cleaned within the room.

From the above it will be apparent that all portions of the sash members may be rcadilycleaned from inside the room. Furthermore, ventilation may be secured either by sliding the upper lor lower sash or both, or by swinging any or all of the sash sections inwardly.

While I' have illustrated and described the preferred embodiment of my invention, itv will be understood that changes may be made in the details thereof without departing from the spirit of the invention and I desire to be limited only by the state of the prior art and the appended claims.
